Depreciate is a verb that means to lower in honor or value.

Our word of the day comes from the Latin word pretium (PRAY tee um) which means ‘price.’ With the addition of the prefix D-E, we get a word that means to ‘lower’ the price of value. The word can be used to refer to the value of a number of things, for example: I don’t think it was a good idea to have a pet tiger in our living room. I’m afraid that the damage he’s done will cause our home to depreciate in value. After all, walls and floors that have been scratched  and chewed up tend to be worth less on the market.
